《数学课程标准》把“空间观念”作为培养学生初步的创新精神和实践能力的一个重要学习内容。我们传统的教学方法对学生空间观念的形成难度相对比较大,学生空间观念形成的过程过于简单化与形式主义,导致学生的空间观念相对薄弱。利用多媒体技术能根据教学需要将教学内容实现大与小、远与近、动与静、快与慢、整与散、虚与实之间的相互转换,能突破时间和空间
Mathematical Curriculum Standards takes Space Concept as an important learning content in cultivating students’ initial innovative spirit and practical ability. Our traditional teaching method is more difficult to form students ’concept of space and simplifies the forming process of students’ space concept and formalism, resulting in a relatively weak student’s space concept. The use of multimedia technology can be based on the teaching needs of teaching content to achieve large and small, far and near, dynamic and static, fast and slow, whole and scattered, the conversion between virtual and reality, can break through the time and space
